I know it’s several months late, but I just got through watching a film done by the Discovery institute, on the Cambrian “explosion,” called “Darwin’s Dilemma: The Mystery of the Cambrian Explosion.” There are a few details that should be addressed about it. But, before I go into any kind of detail, yes, it should be pointed out that this is mostly the same kind of Creationist bull that I thought it would be, just a bit more sophisticated than the usual Creationist arguments made about the Cambrian radiation.

At first, typical of Creationist claims, Jonathan Wells makes the well-worn claim about life forms before and during the Cambrian. He compares the entire 3.8 to 4 billion years of life to a twenty-four hour day saying that for the first 21 hours, there were only unicellular life forms, and then the Cambrian life forms came into existence on the scale of a two minutes. This is an attempt to make the Cambrian radiation appear “sudden” A few minutes later, Wells then says something on the lines of that it could have happened over night which is complete bogus because it lasted at least 10 to 25 million years. Though there are higher estimates that go as high as 35 million years or more. The film says that fossil evidence shows that those estimates are too high, but it doesn’t give convincing details.

The film, however does mention the existence of other life forms, like the Ediacaran fauna which existed before the Cambrian, as well as fossil embryos. . . . Oh, about the fossil embryos, the film uses them to address the idea that pre-Cambrian fossils are not preserved because they were too soft. It is pointed out that these embryos were from soft-bodied organisms, and that they existed tens of millions of years before the Cambrian. From that, it is reasoned that if the appeal to pre-Cambrian organisms being too soft for preservation cannot be used. As the film argues this, the Discovery Institute seems to have missed a major implication of fossil embryos several millions of years before the Cambrian “explosion.” Think about it: Those embryos had to have come from precursor ancestors, and that would therefore show that the Darwinian prediction of the existence of simpler pre-Cambrian life. It shows, therefore, that such organisms did in fact exist, but that they were rarely ever fossilized. Fossilization is already a rare enough occurence without the organisms being much softer than is accustomed. But, another detail the DI seems to have missed: I do not remember any scientist ever saying that soft-bodied, pre-Cambrian fossils could never be preserved. They can be, it’s just much more of a novelty. Correct me if I am wrong, but I think the Discovery Institute is attacking a strawman.

Something I find exceptionally interesting is the interest that the film takes in fossils from southern China. All along, citing these fossils as evidence for their conclusion, I’m left to wonder why other fossils from China are ignored. In pre-Cambrian deposits dating from the Doushantou Formation, evidence of animal life in the form of adult Cnidirians was found. Among the finds were fossilized embryos and larvae tat resembled Anthrozoans. Not to mention, there s also evidence of cnidirian body plans with anthozoan affinity. An implication of this find is that stem groups of bilaterians were also present between 25 to 45 million years before the Cambrian “explosion.” — Then, also there is more recent evidence from the same formation that complex, bilatarians existed between 40 to 55 million years before the Cambrian. — These fossil finds I cited were made in the first half of the last decade, between 2002, and 2005. These finds alone would show that the Cambrian “explosion” was likely less explosive. In contrast, the film Darwin’s Dilemma was released in September, 2009. Why didn’t the Discovery Institute include these fossil finds? Because of ignorance or bias? You make the call. — I go into more detail in my previous post entitled “The Truth on the Cambrian ‘explosion.’“

Between scenes, the Discovery Institute indulges in the usual Creationist quote mining from well-known scientists about the appearance of the Cambrian fauna in the fossil record, but prominently Stephen Gould. Personally, I found that somewhat disrespectful since he is dead with his statements still being hijacked. Then also, they use a very selective quote from Richard Dawkins about the Cambrian’s abruptness in which he says, “It’s as though they were just planted there, without any evolutionary history.” You just have to realize that Dawkins is an Atheist and a major anti-Creationist to realize that he ultimately was not endorsing that view. Besides, as he proposes a little later that “it might be that many of these animals had only soft parts to their bodies: no shells or bones to fossilize,” a view which the film goes out of its way to attempt refuting. — The Quotes from Charles Darwin can be dismissed since they are 151 years out of date, and do not reflect the research accomplished since he published his theory.

A final claim made is on genetic information, and questioning whether or not Darwinian mechanisms can produce it. After deciding that it cannot, they resort to their typical “designer did it” cop-out. They try to rationalize their logic by saying that information is the product of intelligence, yada, yada . . . . I’m not going to even bother to refute the typical argument from ignorance.

Basically, the film really doesn’t address anything that hasn’t been debunked before, it just seems to be a bit more sophisticated, and a bit more informative than other pieces of Creationist propaganda, but that’s probably because it admits to the existence of some fossils from before the Cambrian. I guess from that, it is the “best” Intelligent Design film I’ve ever seen, but that isn’t saying much. Mostly, the only real thing this film has going for it is its graphics, though I have seen better. I guess one of its goals is to dazzle the uninformed layperson with its computer graphics? Who can tell? The Discovery Institute may accept the scientific age of the earth, but other than that, they aren’t much better than ICR.

Scientists have overwhelming evidence to demonstrate that Evolution is not only a theory, but also a fact. So considering that, how is it that Creationists seem to win the debates? — Of course, a Creationist may simply assume that the Creationist wins because the Evolutionist is wrong. But a better look at the subject shows that this isn’t the case at all. There are several reasons Creationists seem to carry the day, and none of them have anything to do with being on the right side. And there are several reasons why Scientists are reluctant to debate with Creationists, and it isn’t because they are on the “wrong” side either.

If you have studied Evolution and know the scientific method, then you will know how Evolution works — I hope, at least. Therefore, I would also hope that you would also be able to pick out arguments made by Creationists that are totally absurd, though they may seem reasonable to the lay person. I see this happen a lot in Kent Hovind debates. — I just watched one, and I found myself getting a headache when he made an illustration about the “evolution of silverware.” Knowing what was coming, I simply fast forwarded through that. In another video I saw, he debated Ben Waggoner from the University of Central Arkansas who, although he undoubtedly knew his stuff, was not prepared for the beating he received. — In fact, the only hostile audience that he had that I know about was when he spoke at Berkley University in which several students called him out.

A major important reason why Creationists seem to win debates is that they seem to usually debate in front of friendly audiences. In other words, most people in the audience have already decided that Evolutionary theory is false, and the reason they are there is to see the “lost” evolutionist get trounced by their champion. — Donald Prothero, a leading professor of Geology, described a time when he accepted a challenge to debate Duane Gish. In the end, during the questions and answers segment, he received several irrelevant and offensive questions such as “Are you going to hell?” or “Are you a sexual pervert?” The audience was not interested in the evidence, but only in seeing the Evolutionist get defeated. Ultimately, he decided not to debate Gish again since it was a waste of time.

Another reason is that Creationists tend to dominate the debate. They have better debating skills than most Scientists because they have more practice at it. Scientists are usually busy with research, so they don’t have as much time to go out and debate. — Creationists also tend to shoot out too much drivel in only a few seconds which is very difficult to refute as quickly as it gets said. And due to the formats and time limits of these debates, the poor scientist is not free to give an adequate answer.

Creationists shoot out arguments like “Life could not have originated by chance,” and “the big bang is false.” — The bull of Creationists using these arguments is that they are not part of Evolutionary theory, even though Creationists don’t seem to see the difference between Biology and Cosmology. These arguments are made to leave the impression that the Evolutionist has no basis for his acceptance of Biological Evolution, and that the theory of evolution is therefore nonsense or “stupid,” as Kent Hovind puts it. — Were I to debate a Creationist who brings these two subjects up, I would simply say “I am here to defend Evolution, not the Big Bang, and not Abiogenesis.”

On the occasions that I do talk with Creationists, I usually run into arguments made against strawman versions of evolution rather than the recognized theory at all. One of them is the idea that evolution “must” lead to increasing complexity, and that the Uniformitarian principle (of Geology, not of evolutionary biology) means that accumulation of all geologic layers was all done slowly with no exception. These arguments are common in the Young Earth Creationist community in particular, however they are based on false premises. Evolutionary theory does not make the prediction that everything has to become more complex, and the principle of uniformitarianism (which is Geology, not evolution) does not dictate that all layers took long periods of time to form.

There is also the fact that it is near impossible to give enough information about how evolution works in just one day. There are reasons why evolution related classes such as Biology and Physical Anthropology take whole semesters. It takes whole semesters to teach the basics of these classes. So the playing field for debates is hardly even at all.

Then there is the fact that Creationists tend to move the goal posts on the scientists. — Kent Hovind’s $250,000 challenge is a great example of this. His challenge pretty much says that even if we could produce evolution, abiogenesis, and the big bang in the lab, it still wouldn’t count because we would still have to prove God had nothing to do with it. Considering that I am a Christian, and therefore believe in God, I see this as ludicrous. The requirements are so unreasonable, it is no wonder not many (if any) scientist has even bothered with this challenge. –Also when given antibacterial resistence as an example, he simply said that no matter what, that bacteria would still not be immune to a sledge-hammer, as if Evolutionary theory makes any such prediction.

Then when it comes to the fossil record, he says “Fossils can’t be used as evidence for evolution because you can’t prove they had any kids.” In other words, no evidence is good enough. Also, it demonstrates he has no understanding about why and how fossils are used. Nobody is saying that a particular fossil is our ancestor, but that it has traits we would expect of what a potential ancestor would have. Hovind was positioning himself in a way that he could be able to dismiss any and all evidence for that abominable theory that he despises so that he wouldn’t have to truly deal with it.

The final reason why Scientists don’t debate with Creationists is they just don’t think it’s worth it. — Richard Dawkins, for example, refused to debate with the Muslim Creationist Harun Yahya when he was challenged saying he didn’t want to give him status. — Also, Kenneth Miller, another top scientist described a time when he accepted a Creationist challenge and asked Steven Gould for help,

I called Steve up and then I explained to him that I was preparing for a debate with a scientific creationist. And I asked him if he could help me out with a couple of arguments. And to my amazement, he stopped me short. And he said, `Ken, I’d like to remain your friend. I’d like to be on good terms with you, but I don’t think it’s wise to debate these guys. I don’t think it’s appropriate to give them a platform for their misguided and misleading views. And if you’re going to debate this fellow, I won’t help you, I won’t provide any assistance, and I won’t even talk with you.’

The truth is, Scientists don’t want to debate Creationists simply because they don’t want to give Creationists status where status is not due. It is not because they are “wrong” and have no evidence to support their claims. It is that the playing field is hardly level which, by the way, also doesn’t make for a good debating forum when you have a whole audience that is intellectually hostile to the scientist. — Also, another reason why they may not want to debate with them is because it may create the impression that Evolutionary theory is controversal in the scientific community.
